Model-based fault detection systems are a type of fault detection system that uses mathematical models of the system being monitored to detect and diagnose potential problems. These models can be based on physical laws, engineering principles, or data-driven approaches.

Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system.
For fault diagnosis a knowledge based procedure is required, because also qualitative information in form of heuristic symptoms have to be taken into account.
